32. Option to Extend Term. Provided that Landlord has not given Tenant notice of
default more than two (2) times in the immediately preceding twelve (12) months,
that there then exists no event of default by Tenant under this lease nor any
event that with the giving of notice and/or the passage of time would constitute
a default, and that Tenant or a person or entity to whom Tenant has the right to
assign this lease or sublet the Premises without Landlord's prior written
consent pursuant to Section 18(a) of this lease are the sole occupants of the
Premises, Tenant shall have the right and option to extend the Term for two (2)
additional periods of thirty-six (36) months each, exercisable by giving
Landlord prior written notice, at least nine (9) months in advance of the
Expiration Date or the first extended Expiration Date, as the case may be, of
Tenant's election to extend the Term; it being agreed that time is of the
essence and that this option is personal to Tenant and to any person or entity
to whom Tenant has the right to assign this lease or sublet the Premises without
Landlord's prior written consent pursuant to Section 18(a) of this lease and is
non-transferable to any other assignee or sublessee (regardless of whether any
such assignment or sublease was made with or without Landlord's consent) or
other party. Such extension shall be under the same terms and conditions as
provided in this lease except as follows:

     (a) the first additional period shall begin on the initial Expiration Date
and thereafter the Expiration Date shall be deemed to be the date which is
thirty-six (36) months after the initial Expiration Date;

     (b) the second additional period shall begin on the first extended
Expiration Date and thereafter the Expiration Date shall be deemed to be the
date which is seventy-two (72) months after the initial Expiration Date;

     (c) there shall be no further options to extend;

     (d) The minimum annual rent for the first year of each additional term
shall be equal to the greater of (i) the minimum annual rent then being paid by
Tenant hereunder, or (ii) 95% of the fair market rental value of the Premises,
determined pursuant to subsection (e) hereof. The minimum annual rent for each
subsequent year of each additional term shall increase by $0.50 per rentable
square foot over the minimum annual rent payable in the immediately preceding
year. For purposes hereof, "fair market rental value of the Premises" shall be
the then prevailing fair market rental value for tenants leasing space of
comparable size in comparable buildings in the Sunrise, Florida area for the
same period of time (taking into account such leasing and economic terms as are
then obtained in the market).


                                       R-3

<PAGE>

     (e) For purposes of this Section 32, if Landlord and Tenant cannot agree as
to the fair market rental value within thirty (30) days after receipt of
Tenant's notice to Landlord under subsection 32(a), the fair market rental value
shall be determined by appraisal. Within ten (10) days after the expiration of
such thirty (30) day period, Landlord and Tenant shall give written notice to
the other setting forth the name and address of an appraiser designated by the
party giving notice. All appraisers selected shall be members of the American
Institution of Real Estate Appraisers and shall have had at least ten (10) years
continuous experience in the business of appraising office buildings in the
greater Sunrise, Florida area. If either party shall fail to give notice of such
designation within the time period provided, then the party who has designated
its appraiser (the "Designating Party") shall notify the other party (the
"Non-Designating Party") in writing that the Non-Designating Party has an
additional ten (10) days to give notice of its designation, otherwise the
appraiser, if any, designated by the Designating Party shall conclusively
determine the fair market rental value. If two appraisers have been designated,
such appraisers shall attempt to agree upon the fair market rental value. If the
two appraisers do not agree on the fair market rental value within twenty (20)
days of their designation, the two appraisers shall designate a third appraiser.
If the two appraisers shall fail to agree upon the identity of a third appraiser
within five (5) business days following the end of such twenty (20) day period,
then either Landlord or Tenant may apply to the American Arbitration
Association, or any successor thereto having jurisdiction, for the settlement of
the dispute as to the designation of the third appraiser and the American
Arbitration Association shall designate a third appraiser in accordance with the
Real Estate Valuation Arbitration Rules of the American Arbitration Association.
The three appraisers shall conduct such hearings as they may deem appropriate,
shall make their determination of fair market rental value in writing and shall
give notice to Landlord and Tenant of such determination within twenty (20) days
after the appointment of the third appraiser. If the three appraisers cannot
agree upon the fair market rental value, each appraiser shall submit in writing
to Landlord and Tenant the fair market rental value as determined by such
appraiser. The fair market rental value for the purposes of this paragraph shall
be equal to the arithmetic average of the two closest fair market rental values
submitted by the appraisers. Each party shall pay its own fees and expenses in
connection with any appraiser selected by such party under this paragraph, and
the parties shall share equally all other expenses and fees of the arbitration,
including the fees and expenses charged by the third appraiser. The fair market
rental value as determined in accordance with the provisions of this Section
shall be final and binding upon Landlord and Tenant.

33. Waiver of Jury Trial. Landlord and Tenant by this subparagraph waive trial
by jury in any action, proceeding, or counterclaim brought by either of the
parties to this lease against the other on any matters whatsoever arising out of
or in any way connected with this lease, the relationship of Landlord and
Tenant, Tenant's use or occupancy of the Premises, or any other claims
(including without limitation claims for personal injury or property damage),
and any emergency statutory or any other statutory remedy.

34. Brokers: Recognition and Indemnity.

     (a) Tenant and Landlord represent and warrant to each other that U.S.
Realty Advisors, Inc. is the only broker or finder that either has had any
dealings, negotiations or consultations with relating to the Premises or this
transaction and that no other broker or finder called the Premises to Tenant's
attention for lease or took any part in any dealings, negotiations or
consultations relating to the Premises or this lease. Such named broker is
entitled to a commission from Landlord pursuant to a separate agreement between
Landlord and such broker.

     (b) Tenant agrees to be responsible for, indemnify, defend and hold
harmless Landlord from and against all costs, fees (including, without
limitation, attorney's fees), expenses, liabilities and claims incurred or
suffered by Landlord arising from any breach by Tenant of Tenant's foregoing
representation and warranty. Landlord agrees to be responsible for, indemnify,
defend and hold harmless Tenant from and against all costs, fees (including,
without limitation, attorney's fees), expenses, liabilities and claims incurred
or suffered by Tenant arising from any breach by Landlord of Landlord's
foregoing representation and warranty.

35. Consents. Whenever the consent of a party hereto is required hereunder, such
consent shall not be unreasonably withheld, conditioned or delayed.

36. Parking. The parking lots appurtenant to the Property contain 4.5 parking
spaces per 1000 rentable square feet in the Building. So long as Tenant's leases
in the Building and the Adjacent Building remain in full force and effect,
Tenant and its Agents shall have the right to the exclusive use, without charge,
of those parking spaces shown as "Tenant's Exclusive Parking" on Exhibit "A"
attached hereto. At Tenant's option, Landlord shall designate some or all of
such exclusive parking spaces as reserved spaces by appropriate signs or
painting, but shall have no duty to enforce such exclusive or reserved parking.
To the extent additional spaces in the parking lots are available, Tenant and
its Agents shall have the right to use same, without charge on a non-exclusive
basis, provided that such use does not deprive other tenants in the Building
from using their respective Proportionate Shares of the spaces in the parking
areas in violation of their respective leases.

37. Additional Contiguous Space. If and when any other space in the Building or
in the adjacent building at 13650 N.W. 8th Street (the "Adjacent Building")
(individually, the "Additional Space") first becomes available for rental during
the term of this lease and provided that Landlord has not given Tenant notice of
default more than two (2) times during the immediately preceding twelve (12)
months, that there then exists no event of default by Tenant under this lease
nor any event that with the giving of notice and/or the passage of time would
constitute a default, and that Tenant is the sole occupant of the Premises,
Tenant shall have the right of first offer to lease all of each Additional
Space, subject to the following:

     (a) Landlord shall notify Tenant when each Additional Space first becomes
available for rental by any party, other than the tenant then in occupancy of
such Additional Space and Tenant shall have five (5) business days following
receipt of such notice within which to notify Landlord in writing that Tenant is
interested in negotiating terms for leasing such Additional


                                       R-5

<PAGE>

Space and to have its offer considered by Landlord prior to the leasing by
Landlord of such Additional Space to a third party. If Tenant notifies Landlord
within such time period that Tenant is so interested, then Landlord and Tenant
shall have ten (10) business days following Landlord's receipt of such notice
from Tenant within which to negotiate mutually satisfactory terms for the
leasing of such Additional Space by Tenant and to execute an amendment to this
lease incorporating such terms or a new lease for such Additional Space.

     (b) If Tenant does not notify Landlord within such five (5) business days
of its interest in leasing such Additional Space or if Tenant does not execute
such amendment or lease within such ten (10) business days, if applicable, then
this right of first offer to lease such Additional Space will lapse and be of no
further force or effect and Landlord shall have the right to lease all or part
of such Additional Space to any other party at any time on any terms and
conditions acceptable to Landlord.

     (c) This right of first offer to lease each Additional Space is a one-time
right if and when each Additional Space first becomes available, is personal to
Tenant and is non-transferable to any assignee or sublessee (regardless of
whether any such assignment or sublease was made with or without Landlord's
consent) or other party, and with respect to the Adjacent Building, is only
effective so long as both the Building and the Adjacent Building are owned by
the same party.

including, without limitation, maintenance, repair and replacement of the HVAC
systems appurtenant to the Premises, and shall provide Tenant with trash removal
and janitorial services pursuant to a cleaning schedule attached hereto as
Exhibit "G"; provided that Landlord shall have no responsibility to make any
repair until Landlord receives written notice of the need for such repair. The
services to be provided by Landlord pursuant to this Section 7(g) (the 'Premises
Direct Services') include (1) janitorial services per Exhibit 'G', emergency
day-time clean-up needs, janitorial supplies, semi-annual interior window
cleaning, exterminating, trash removal and recycling, (2) Premises maintenance
and repair, including supplies and parts (e.g., lighting, ceiling tiles,
plumbing, mechanical, etc.), 24-hour on-call maintenance technicians and

semi-annual indoor air quality testing, preventive maintenance and on-call
repairs and maintenance, including parts and labor. The costs for Premises
Direct Services (the 'Premises Direct Operating Expenses') shall be provided at
the sole expense of Tenant. Tenant shall pay to Landlord the Premises Direct
Operating Expenses in equal monthly installments in the amount set forth in
Section l(d)(iii) (prorated for any partial month), from the Commencement Date
and continuing throughout the Term on the first day of each calendar month
during the Term, as additional rent, without notice, demand or setoff. Landlord
shall apply such payments to the Premises Direct Operating Expenses owed to
Landlord by Tenant pursuant to this Section 7(g). The amount of the Premises
Direct Operating Expenses set forth in Subsection l(d)(iii) represents the
estimated Premises Direct Operating Expenses during the first calendar year of
the Term on an annualized basis; from time to time Landlord may adjust such
estimated amount if the estimated Premises Direct Operating Expenses increase.
By April 30th of each year (and as soon as practical after the expiration or
termination of this lease or at any time in the event of a sale of the
Property), Landlord shall provide Tenant with a statement of the actual amount
of such Premises Direct Operating Expenses for the preceding calendar year or
part thereof. Landlord or Tenant shall pay to the other the amount of any
deficiency or overpayment then due from one to the other or, at Landlord's
option, Landlord may credit Tenant's account for any overpayment. Tenant's
obligation to pay the Premises Direct Operating Expenses pursuant to this
Section 7(g) shall survive the expiration or termination of this lease.

               Premises Direct Operating Expenses for calendar year 2004 on an
annualized basis shall not exceed $0.91 per rentable square foot of the
Premises. Commencing with calendar year 2005, annual increases in Premises
Direct Operating Expenses on an annualized basis shall not exceed 6% more than
such Premises Direct Operating Expenses for the prior calendar year on an
annualized basis. In the event an increase in Premises Direct Operating Expenses
on an annualized basis in any year is more than 6%, the excess may be billed to
Tenant


                                      R-ll

<PAGE>

in any future year in which the increase in Premises Direct Operating Expenses
on an annualized basis is less than 6% as long as in any year Premises Direct
Operating Expenses are not in excess of 6% more than the Premises Direct
Operating Expenses in the immediately preceding year on an annualized basis."

               Notwithstanding anything to the contrary herein contained, Tenant
shall have the right, at any time during the Term, upon thirty (30) days prior
written notice to Landlord, to provide its own janitorial services with respect
to the Premises. In such event janitorial services shall no longer be included
in Premises Direct Services and appropriate adjustments shall be made to
Premises Direct Operating Expenses for the current calendar year and, for
purposes only of determining the maximum increase in Premises Direct Operating
Expenses for the current calendar year, appropriate adjustments shall be made to
Premises Direct Operating Expenses for the prior calendar year to reflect
janitorial expenses for the same length of time Landlord provided same in the
current calendar year.

43. Additional Provisions Relating to Signs. Section 8 of the lease is amended
as follows:

     (a) on the second (2nd) line after "Landlord", by adding ", such consent
not to be inreasonably withheld".

     (b) by adding at the end thereof:

          "Subject to Landlord obtaining all necessary governmental approvals
therefor, Landlord shall rename the property consisting of the Building and the
Adjacent Building as the 'NationsHealth Center'.

          Subject to Tenant obtaining Landlord's consent and all necessary
governmental and owner association approvals therefor, Tenant at its sole
expense shall be permitted to install and maintain identification signs in
existing colors specifying Tenant's name and logo (i) on each of the three (3)
sides of the exterior of the Building abutting the Premises, (ii) on the wall
space immediately adjacent to its main entrance doors to the Premises, and (iii)
on an additional monument sign at the entrance to the Property. Landlord shall
cooperate with Tenant, at no expense to Landlord, in seeking and obtaining
required approvals. Landlord agrees that, other than Tenant's signs, no other
exterior signage shall be permitted to be installed on the Building except for
Building standard tenant identification signage.

          Landlord further agrees that, so long as no space in the Building or
the Adjacent Building is available for lease, it will not maintain a leasing
sign on the Property."

44. Additional Provisions Relating to Mechanics' Liens. Section 10 is deleted in
its entirety and replaced with the following:

          "10. Mechanics' Liens. The property shall not be subject in any way to
any liens, including construction liens, for improvements to or other work
performed with respect the Property by or on behalf of the Tenant. Tenant shall
pay promptly any contractors and

has committed a default of one or more of its obligations under the lease. The
beneficiary of the letter of credit shall be Landlord, and such letter of credit
shall be transferable by Landlord to any entity succeeding to Landlord's
interest in the Property, without cost to Landlord or its successors in

(60) days prior to its expiration so that it continuously remains in effect
through the Expiry Date. Notwithstanding any provision above to the contrary,
failure of Tenant to renew or replace the letter of credit in accordance with
the foregoing requirements shall be deemed a default by Tenant under the terms
of this lease which shall not require the giving of notice or the allowance of
any grace period, and shall entitle Landlord to immediately draw funds under the
letter of credit (an "Early Draw"), in addition to any other remedies provided
for in this lease or under applicable law. In the event of an Early Draw,
Landlord shall hold and apply the funds so drawn as if cash in such amount had
been posted by Tenant as the Security Deposit."

to be present with Tenant at the installation or removal.

     (e) Tenant shall maintain the Generator in a safe, good and orderly
condition. The installation, maintenance, repair and removal of the Generator
shall be performed at Tenant's sole expense in a manner which will not impair
the integrity of, damage or adversely affect the warranty applicable to, any
portion of the Property.

     (f) The Generator will remain Tenant's property throughout the Term of the
lease and, no later than the expiration or sooner termination of the Term, at
Tenant's sole expense, Tenant shall remove the Generator and all wiring
therefrom to and through the Building and repair any resulting damage, including
without limitation, damage to landscaping or paving, or, at Landlord's option,
Tenant shall also be responsible for restoring all affected areas to the

with all Laws and Requirements in connection with the removal of the Generator
and shall deliver to Landlord copies of all required permits and approvals in

Property therefor. Without limiting the foregoing, Tenant solely shall be
responsible for any damage or injury caused by or in any way relating to the
Generator, including, but not limited to, damage or injury to persons or
property, including the Property, caused by reason of any leaking of fuel
therefrom.

     (h) In the event the cost of Landlord's insurance on the Building is
increased as a result of the installation of the Generator, Tenant shall pay for
the increase in such insurance as set forth in subsection 7(c)(iv) of this
lease.
